RATIONALE: Drugs used in chemotherapy, such as gemcitabine hydrochloride and cisplatin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Temsirolimus may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving gemcitabine hydrochloride and cisplatin together with temsirolimus may kill more tumor cells.

PURPOSE: This phase I/II trial is studying the side effects and best dose of temsirolimus given together with gemcitabine hydrochloride and cisplatin as first-line therapy in treating patients with locally advanced and/or metastatic transitional cell cancer of the urothelium.

A Phase I/II Single-Arm Trial to Evaluate the Combination of Cisplatin and Gemcitabine With the mTOR Inhibitor Temsirolimus for First-Line Treatment of Patients With Advanced Transitional Cell Carcinoma of the Urothelium

Toxicity during and after treatment according to NCI CTCAE v 3.0 (phase II) [ Designated as safety issue: Yes ]

Estimated Enrollment:

99

Study Start Date:

February 2008

Primary Completion Date:

January 2010 (Final data collection date for primary outcome measure)

Detailed Description:

OBJECTIVES:

Primary

To determine a safety profile of temsirolimus in combination with cisplatin and gemcitabine hydrochloride, including dose-limiting toxicities (DLTs) and maximum-tolerated dose (MTD) in patients with locally advanced and/or metastatic transitional cell carcinoma of the urothelium. (phase I)

To determine the recommended dose for the Phase II stage of the trial and subsequent studies. (phase I)

To assess progression-free survival (PFS) at six months from date of enrollment. (phase II)

Secondary

To determine the pharmacokinetic profile of temsirolimus in combination with cisplatin and gemcitabine hydrochloride. (phase I)

To determine toxicity during and after treatment in these patients. (phase II)

OUTLINE: This is a multicenter, phase I dose-escalation study of temsirolimus followed by a phase II study.

Patients receive gemcitabine hydrochloride IV over 30 minutes on days 1 and 8, cisplatin IV over 3-4 hours on day 1, and temsirolimus IV over 30 minutes on days 1 or 2, 8 or 9, and 15. Treatment repeats every 21 days for up to 6 courses in the absence of disease progression or unacceptable toxicity.

Blood specimens may be collected periodically for pharmacokinetic studies.

After completion of study treatment, patients are followed at 6 months and 1 year.
